Tru64 BIND Client won't stay working

[BrianT_1]

I'm using a Tru64 4.0E Alpha that I had to rebuild after a crash. I can't get the BIND client to resolve names. I've used bindconfig to set it up and all the values and files appear correct. rc.config shows BIND is configured as a client and svc.conf shows hosts=local,bind,yp. /etc/hosts contains the correct values. when I try to look up a host, though, it fails and I can't ping any of the name servers. As far as I know, my routes are correct. Could this me a matter of the route daemon not working? I can access the system via telnet and I can telnet out from it as well using IP addresses, but not to all the systems I need to reach, so I think there's something wrong with the routing. How do I check?

Actual command? Actual results?

Are you using YP (NIS)?

As a non-psychic with no information from
you, how can I argue?

Are you running routed (or whatever), or are
you using static routes?

netstat -rn

No, I just accepted the defaults.

routed.

> netstat -rn

Node> netstat -rn

I don't see the default gateway in the netstat output, but I know it's defined necause it's in /etc/gateways.

net 10.0.0.0 gateway 10.33.0.11 metric 1 active

and this is in routes

default 10.33.0.11

Ok. And what are the addresses of the name
servers? (Do you have a route (or routes) to
them?)

> I don't see the default gateway [...]

I've never used routed, so I know nothing,
but I wouldn't bet that anyone looks at
/etc/gateways (or any other static route
stuff) if you use routed. Knowing nothing,
I'd need to look at the "rc" scripts to see
who does what when at system start-up.

> 10.33/18 10.33.1.99 U 29 56257 tu0

> default 10.33.0.11

And 10.33.1.99 is not 10.33.0.11.

Again, I've never tried mixing a static route
into a routed situation, but you might try
something like
route add default 10.33.0.11
(or whatever syntax "man route" suggests) to
see if that helps. (See if "netstat -rn"
actually changes, too.)

Do you have any other, similar (working)
systems? How are they configured?

By using the route command to add the default route manuall, the BIND client started working. While I don't understand why /sbin/init.d/route didn't pick it up from /etc/routes, I at least know what to do if the problem recurs. I can take my time figuring out why the problem occurred. Thanks.

I can see them now. I see no one looking at
"/etc/gateways":

urtx# pwd
/sbin/init.d
urtx# grep gateways *
urtx#

but "/sbin/init.d/routes" does seem to
consider "/etc/routes". Around here:

urtx# cat /etc/routes
default 10.0.0.1
urtx# cat /etc/gateways
urtx#

urtx# sizer -v

Things may have been different in the old
days, of course.
